Device at a card, in which a multiple number of working items are allocated to a roller as for example drum. The invention refers to a device at a card, in which in pre and/or post carding area a multiple number of working items, as for example fixed carding items,, suction equipment, eliminating knife, and the equivalent lying opposite to each other and - seen in circumferential direction of the roller adjacent to each other are assembled to a roller wherein out of at least two working items one module is formed. In a known device (DE 3855776A1) modules are provided with two and more working items and are fixed on card side frame. A cleaning device in shape of a suction unit is present before which a guide rod and after which a measuring rod are assembled. It is disadvantageous that this device does not make possible an influencing of the composition of eliminated foreign items (waste composition) and a removal of neps- The assignment therefore lies at the base of the invention, to procure a device of the type described at the outset, which avoids the mentioned disadvantages, which permits in particular a change or rather influencing of waste composition and the removal of neps. The solution of this assignment takes place through the distinguishing features of claim 1. Through the measures as per invention it turns out well, to improve considerably the elimination of troubling foreign materials and/or neps. A special advantage exists therein, that a multifunctional assembly of working items is made possible. Through it,, a flexible matching to fibre materials in order to meet high quality requirements in the materials under production, turns out well, in particular on ground of module design and the uniform angle stretching to reduce considerably time expenditure for the exchange of worn out working items at higher precision of the assembly of replaced items. The claims 2 to 17 H^tve in content advantageous further developments of invention. It show; Fig.1 Schematic side view of a card with the device as per invention Fig.2 an execution shape of device with two modules for elimination of foreign materials in pre carding area. Fig.3 an execution shape of device with two modules for elimination of neps in post card area. Fig.4 An execution shape of device with three modules for elimination of foreign materials and neps in the pre carding area and Fig.5 an execution shape of device with three modules for elimination of foreign materials and neps in the post carding area. Fig.l shows a card as for example Truetzschler high capacity card DK 903, with feed roller 1, feed table 2, licker in 3a» 3b, 3c, drum 4, doffing cylinder 5, stripping roller 6, squeeze roller 7, 8, non-woven fleece guide item 9, web trumpet 10, draw box 11,, 12, revolving flat 13, with flat rods 14, can 15, and can coiler 16. The direction of rotation of rollers are shown with bent arrows. With A the working direction is denoted. The device 17 as per invention can be assembled as for example at the locations B and/or C at the drum 4. At location B, as per Fig.2 - seen in direction of rotation 4a of the drum - in succession two modules B1, B2, with in each case a fixed carding item 18a, a suction hood 19a with eliminating knife 20 and eliminating opening 21 and a pressure item 17a with pressure bar 22 are present. Through the successively connected module B1, B2 an essential improvement of elimination of foreign bodies like trash, collection parts, leaf residuals end the equivalent are made possible. At location C corresponding to Fig.3 - seen in direction of rotation 4a of the drum 4 successively two modules C1,( C2 with in each case a pressure item 17b, with pressure bar 22, a suction hood 19b with eliminating knife 20 and eliminating opening 21 and a fixed carding item 18b are assembled. Through the successive connection of modules CI, C2 a considerable improvement of the elimination of neps are realised. With 4b set of the drum is denoted. With 26 the cover 26 lying opposite to the set 4b is denoted. As per Figure 4 and 5 in the pre carding area B and in the post carding area C in each case three modules are present, from which in each case two modules B1, B3, CI, C3 of foreign body elimination and a module B2, C2 of nep eliminating serve. The positions provided with number are recorded with following working items : With 23 a suction hood is denoted- with 24 a neutral cover item is denoted. The modules B1, B2, B3f CI- C2r C3 are assembled on both extension bends 27a, 27b of the card. The extension bends 27a and 27b are fixed on each side of the card to a card side frame 25a or rather 25b.. The extension bends 27a and 27b are adjustable over at lest three adjusting screws 28a7| 28a2., 28a3 or rather 28b,, 28b2, 28b3. In this way the distance a (Fig.2, 3) between working items or rather modules and the set of the drum 4 is adjustable. WE CLAIM 1.
